What is happening. I religiously do a 30% ish water change weekly, I have an RODI system and only use that water…I used instant ocean salt and up until this last time everything seemed fine. I don’t have much but my torch and Duncan’s are closing up, and just generally looking like they are dying and my plate doesn’t look far behind!

My parameters are within acceptable ranges. My salinity was a little higher than I normally keep it at 1.034 I normally keep it at 1.025 ish. I bought a new wave maker and when I tested the salinity after the water change it was showing super low so I added more. I can only assume that fluctuation is what did it? i have a 90 gallon tank almost a year old.

If this is a newer tank, you may be cleaning it too often.
How are you testing water and what is age of tank?
What type of tank and what type of filtration?
 
I dont mean to sound too harsh, but you could get a lot more help by listing numbers. "fine" and "all good" unfortunately dont say much
Not too harsh at all. This is the area I’m still super new…don’t laugh but I’ve been using the sticks to test my water. I have no idea which testing products are the best to use and there are so many out there. My salinity though is tested with a Hanna digital salinity tester But I didn’t get an “accurate” reading until I pulled water from the middle of the tank that’s when I realized how high it was.
 
How are you testing for Salinity? My tester needs 30 mins to get back to room temp after each test/calibration otherwise the levels are off.
that is a cool background, I had to look twice because I wasn't sure what I was seeing initially lol
the salinity is way too high, which is probably the problem here
Thank you! I scoured the internet searching for that background! ☺️ Very sad to think I did this to them. Unfortunately I went away for the weekend or I probably could have caught it sooner. When I did I took out some water and replaced it with fresh RODI. What salinity do you recommend?

That’s likely the problem, keep in mind corals do mean maintenance and sticks are not a good way to test.
Test kits I recommend
Nyos for nitrate
Salifert for mag and alk
Red Sea for calcium
Hanna for phosphate

I’m sure there are plenty others that work just as well, but these are my preferred. If you want to keep corals then you are going to have a to pick up test for at least mag calc and alk

You added wave maker and it was low so you added more. Added more salt to the tank? Just looking for clarification because if the salinity was low and you added salt directly to the tank to raise it and it went to 1.034 that could be a problem as could being too low.
Maybe I'm misunderstanding :thinking-face:
